Jackson Star Quilt Block Pattern

The Jackson star quilt block is a beauty. I’ve made it in blues because I like blues, although it is more traditionally made in greens. It’s classified as an eight patch block and I have made it here as a 24″ square finished size.

Cutting requirements for the Jackson star quilt block

3.1/2″ squares: eight white, twelve dark blue, four light blue

3.7/8″ squares: twelve each in dark blue and white, four each in light blue and white

6.1/2″ by 3.1/2″ rectangles: four white

Make half square triangles

Make the half square triangles

Use the 3.7/8″ squares to make half square triangle units. Place a white square right sides together with a dark blue or light blue square and mark a line along the diagonal. Sew a 1/4″ seam either side of the marked line and cut along the line. This will produce two half square triangle units which are now 3.1/2″ squares.

Press the seam allowances towards the blue triangles and trim the two corners where fabric sticks out.

Central part of layout

Make the Jackson star quilt block

I’ve shown the central part of the block first, using two white rectangles for the central square. You could use a 6.1/2″ square or four 3.1/2″ squares if you prefer. On each edge of this square place a pair of light blue/white half square triangles. Note that the two white triangles together make a larger white triangle pointing towards the middle. In each corner of this section place a 3.1/2″ light blue square.

For the first frame around the central area place a pair of dark blue/white half square triangles outside the existing light blue/white half square triangles. Place them so that the four white triangles now form a diamond. On either side of the half square triangles lay two dark blue squares. Use this layout on each edge of the central area.

In the outer frame place a white rectangle in the middle of the top and bottom rows, with two white squares in the middle of each side. On each side of these place a pair of dark blue/white half square triangles. Place these so that the white triangles form larger triangles pointing in towards the middle. Lay a white square in each corner of the block.

Sew the squares together across each row and then sew the rows to each other to complete the Jackson star quilt block.

Basic quilt design

For quilt ideas I have shown a basic Jackson star quilt using four blocks in two rows of two.

Alternate design

As an alternative design, I have used just one block but added three borders to it.

HI Rose, this quilt is stunning in blues. My youngest daughter’s favorite color. I have a ton of fat quarters in various shades blues. This would make a beautiful quilt for her. I printed the directions, so this will occupy most of my day tomorrow with the slo cooker making supper…life is good, especially after retiring.
